When a bird flaps its wings, air is pushed downward. This produces an opposite force that "lifts" the bird into the air. Since a bird's wing is in the shape of an airfoil, it produces some lift even when the bird is just gliding. Birds also rely on the shape of their wings to fly. To start with, their wings are streamlined so the air particles can travel round them smoothly. The bird has equal forces pushing against either side of its wing. To take off, the bird needs to have lift, which means the force pushing the bird up must be stronger than the force pulling the bird down. This can be achieved by making the particles of air flow along the top faster than along the bottom of the wing. Since an equal number of particles must pass along the top and the bottom within the same amount of time, to make them move faster the distance the particles travel on top must be increased. This is why birds have concave wings. The dynamics of bird flight like all physical actions are governed by the laws of physics. In its simplest expression, flying is a balance between two sets of forces. lift and weight, and thrust and drag. Weight is the result of gravity and is reduced as much as possible in birds. Lift is generated by the flow of air over the wings.
Birds are able to fly due to a combination of factors, including their lightweight and aerodynamic body structure, their powerful muscles, and their unique respiratory system that allows for efficient oxygen exchange during flight. Additionally, the shape and arrangement of their feathers help create lift and reduce drag, enabling them to stay aloft.
cats like to chase and eat birds, and birds like to fly to get away from cats.
They are too numerous to list, but here are a few that are still around: Penguins, the Falkland Flightless Duck, Ostrich, Emu, Rheas, Cassowaries, Flightless Comorants, Kiwis, Snoring Rail, Campbell Island Teal, the Kakapo Parrot,
Yes, feathers are a key adaptation related to flight in birds. They are lightweight yet strong structures that provide lift and enable birds to fly. Feathers also play roles in insulation, camouflage, and display.
No, Venus fly traps are not toxic to birds. Birds are not known to be attracted to Venus fly traps for food, as they primarily feed on insects and seeds.
Some birds may fly away from forest fires if they sense danger and are able to escape in time. However, birds that are slower or unable to fly may have a harder time escaping from rapidly spreading fires. Additionally, some birds may seek shelter in bodies of water or other safe areas until the fire passes.
They have hollow bones.
No it makes them fly
Because of their wings that makes them fly longer than other birds
For example: - When watching a scary movie, all viewers are scared. - Or a common one, all birds can fly. -- Just because a person knows that all birds he/she has seen fly, he/she makes the overgeneralization that all birds can fly.
Their bones are hollow which makes the bird light. With its lightness it is able to fly.
It is not only birds that fly. Bats fly and they are not birds.
destroy the head of the skeleton with the bow....
They are water birds that spend most of their time in the ocean diving for food. They cannot fly!
Chickens are first of all birds and in order to fly, birds need to be aerodynamic. Less winf resistance makes it easier to fly so having reproductive organs insinde makes sense.
Most birds can fly. Not all.
To say that birds use wings and feathers to fly, so all birds can fly, would be false. Not all birds can fly. An ostrich is an example of a bird that cannot fly.
It makes them lighter and so it is easier to fly.
